(TSXV: HSTR) (OTCQX: HSTXF) (FSE: RGG1) (\"Heliostar\" or the \"Company\") is pleased to present positive preliminary metallurgical test results as part of the Rescoping Study of the Ana Paula project in Mexico (\"Ana Paula\" or the \"Ana Paula Project\"). Heliostar CEO, Charles Funk, commented, \"These metallurgical results represent a significant step-change in our understanding of the Ana Paula Project. An 80.4% recovery using conventional grind sizes and recovery techniques indicates the High Grade Panel has the potential to be processed through a simple mill flowsheet. The analysis was completed on composite samples collected from a range of locations, host lithologies, and grade ranges throughout the High Grade Panel. Broadly speaking, high-grade gold mineralization has more coarse-grained gold and is easier to recover than the surrounding low-grade halo of mineralization. The High Grade Panel does not display refractory characteristics. These results will lead to additional optimization work and inform the cutoff grades for gold mineralization in next month's planned resource update.\"Summary of Metallurgy ResultsHeliostar submitted eight composite samples, prepared from drill holes completed in the 2023 Ana Paula drill campaign to Blue Coast Research Ltd. Seven samples were collected from the High Grade Panel and one from the footwall to the panel. Composites were generally selected from continuous intervals of similar grade and lithologies from spatially diverse areas of the deposit. Composites were then split into two workflows: the first focused on gold recoveries at various grind sizes using kinetic and carbon in leach (CIL) bottle roll testing, while...
